Exam Questions

1:You are configuring new Windows 98 systems for connection to a NetWare server. After installing the client software and rebooting the system, which of the following information do you need to supply to log in to NDS? (Choose the three best answers.)

  1. Tree name

  2. Username

  3. Domain name

  4. Password

A1: a, b, d. To connect to a NetWare server, you need to supply a valid username and password, as well as the name of the NDS tree to which you want to connect. A domain name is not required because domains, in this context, are associated with Windows NT/2000 based networks. For more information, see the section “Configuring Clients to Access Servers,” in this chapter.
2:Which service must be installed on a Linux system in order to make the file and print capabilities of the server available to clients?

  1. Squid

  2. Samba

  3. DNS

  4. WINS

A2: b. The Samba service can be loaded on a Linux system to provide file and print functionality to Windows clients. None of the other services listed provide this service. For more information, see the section “Configuring Clients to Access Servers,” in this chapter.
3:Which of the following data-link-layer protocols are used to establish a remote access connection? (Choose the two best answers.)

  1. PPP

  2. TCP

  3. SLIP

  4. IPX

A3: a, c. PPP and SLIP are data-link-layer protocols that can be used to establish remote connectivity between two devices. TCP and IPX are both transport-layer protocols. For more information, see the section “Configuring Remote Connectivity,” in this chapter.
4:Which of the following pieces of information are required to configure a system for TCP/IP connectivity? (Choose the two best answers.)

  1. DNS server addresses

  2. Default gateway

  3. IP address

  4. Subnet mask

A4: c, d. To configure TCP/IP, you only need an IP address and the subnet mask. However, without a default gateway, network functionality is limited to the local network segment, and DNS or WINS resolutions are not available. For more information, see the section “Configuring Clients to Access Servers,” in this chapter.
5:You are configuring DHCP functionality on a network that has 100 Windows NT Workstation systems. Which of the following network operating system platforms can you use to supply DHCP server functionality?

  1. Windows 2000

  2. NetWare

  3. Linux

  4. All of the above

A5: d. DHCP is part of the TCP/IP protocol suite and is therefore platform independent. DHCP server functionality is provided by all common network operating systems, so any of the platforms listed would make suitable DHCP servers. For more information, see the section “Configuring Clients to Access Servers,” in this chapter.
6:While troubleshooting a Windows 2000 server, you disable the DNS service. What effect will this have on the network users?

  1. Users cannot receive IP addresses dynamically.

  2. Users cannot contact servers using hostnames.

  3. Broadcast traffic increases.

  4. Systems cannot use VPNs.

A6: b. If you disable the DNS service, users will not be able to contact servers on the network by using the hostnames and will instead have to use IP addresses. Answer a describes the DHCP service, so disabling DNS will not affect IP address assignment. DNS resolutions cannot be achieved via broadcasts, so these will not increase as a result. Answer d is not valid. For more information, see the section “Adding, Modifying, or Removing Network Services,” in this chapter.
7:As the network administrator for a very large network, you have been asked to reduce the traffic generated by the DHCP service. Which of the following would be the best course of action?

  1. Reinstall DHCP.

  2. Increase the DHCP lease time.

  3. Decrease the DHCP lease time.

  4. Manually assign DHCP addresses.

A7: b. If you increase the DHCP lease duration, there will be fewer lease renewal requests on the system. However, this brings with it many other considerations that might make it impractical. None of the other strategies would reduce DHCP-related traffic. For more information, see the section “Adding, Modifying, or Removing Network Services,” in this chapter.
8:You have just added 15 new workstations on a network. Which of the following is the easiest way to assign these systems WINS and DNS configuration information?

  1. Use the LMHOST and HOSTS files.

  2. Provide users with the configuration information.

  3. Use Windows 2000 WINS/DNS Proxy Service (WDPS).

  4. Use DHCP.

A8: d. If you are configuring network settings, by far the easiest way to supply the information to client system is to use DHCP. Answers a and b are valid, but they are both time-consuming. Answer c is invalid. For more information, see the section “Configuring Clients to Access Servers,” in this chapter.
9:When configuring a client to log on to a Windows 2000 domain, which two of the following actions must be completed?

  1. Choose to log on to the Windows NT domain.

  2. Install the Internetwork Protocol Client (IPC).

  3. Select the appropriate tree and context.

  4. Supply the domain name.

A9: a, d. When authenticating to a Windows 2000 server, the domain name must be supplied and the desire to log on to the domain must be selected. Answer b is not a valid answer. Answer c is related to logging on to a NetWare server. For more information, see the section “Configuring Clients to Access Servers,” in this chapter.
